Taxonomic Notes on Persicaria hydropiper (L.) Delarbre (Subiberi)

Öz

Persicaria hydropiper (L.) Delarbre, is a herbaceous annual species distributed mostly in damp places and aquatic habitats of Asia and Europe, including Türkiye. Specimens of the taxon are characterized by taproot, erect stem, elliptic-lanceolate leaf, tubular ochrea, brown glandular perianth and typical trigonous dark brown nut fruits. When the specimens belonging to Persicaria leblebicii (Yıld.) Raus (=Polygonum leblebicii Yıld.), which was published as a new species from our country, and Persicaria hydropiperoides (Michx.) Small, which was given as a new record, were examined, it was determined that they had similar morphological characteristics with P. hydropiper specimens. This morphological similarity is highly supported by phylogenetic analyses based on nrDNA ITS data. This situation shows that the samples given as P. leblebicii and P. hydropiperoides in our country belong to the P. hydropiper. In this study, the extended description, detailed chorology and phylogenetic relationships of the P. hydropiper, which is widespread in Türkiye, was presented in detail for the first time based on newly collected specimens and stored samples in various herbaria, and important contributions were made to the taxonomy of the species.

Subiberi [Persicaria hydropiper (L.) Delarbre] Türü Üzerine Taksonomik Notlar

Öz

Persicaria hydropiper (L.) Delarbre, Türkiye’nin de içinde bulunduğu Asya ve Avrupa’nın daha çok nemli ve sucul habitatlarında yayılış gösteren otsu biryıllık türdür. Taksona ait örnekler kazık kök, dik gövde, eliptik-mızraksı yaprak, boru şeklinde okrea, kahverengi salgılı periyant ve tipik üç köşeli koyu kahverengi fındıksı meyveleri ile karakterize olmaktadır. Ülkemizden yeni tür olarak yayınlanan Persicaria leblebicii (Yıld.) Raus (=Polygonum leblebicii Yıld.) ile yeni kayıt olarak verilen Persicaria hydropiperoides (Michx.) Small taksonlarına ait örnekler incelendiğinde, bunların P. hydropiper örnekleri ile benzer morfolojik özelliklere sahip olduğu tespit edilmiştir. Tespit edilen bu morfolojik benzerlik nrDNA ITS verilerine dayalı filogenetik analizler tarafından da yüksek oranda desteklenmektedir. Bu durum P. leblebicii ve P. hydropiperoides olarak verilen ülkemiz örneklerinin de P. hydropiper taksonuna ait olduğunu göstermektedir. Bu çalışma ile ülkemizde yayılış gösteren P. hydropiper taksonunun genişletilmiş betimi, ayrıntılı korolojisi ve filogenetik ilişkileri yeni toplanmış ve çeşitli herbaryumlarda saklanan örneklere dayalı olarak ilk kez ayrıntılı olarak ortaya konmuş ve türün taksonomisine önemli katkılar sağlanmıştır.
